A railway turntable is a rotating platform used to turn trains or railway cars around. It is often found at train stations or railway yards where trains need to change direction but there is no room for a full track loop. The turntable allows a train to be rotated 180 degrees, making it easier to switch tracks or return in the opposite direction. The platform is typically powered by a motor and can hold the weight of the train as it rotates. This device is especially useful in locations with limited space.
